FDSS technology can detect fire in buses in less than 30 seconds and extinguish it in 60 seconds thereby reducing the risk to life and property to a significant extent.

Demonstrations were given on water mist-based FDSS for passenger compartment and aerosol-based FDSS for engine fire.

DRDO’s Centre for Fire Explosive and Environment Safety (CFEES), Delhi has developed the technology.

The FDSS for passenger compartment comprises a water tank of 80 litre capacity, a 6.8 kg nitrogen cylinder pressurised to 200 bar installed at appropriate location in the bus and a network of tubing with 16 number of atomizers inside the passenger compartment.

The FDSS for engine comprises of aerosol generator with which the fire suppression could be achieved within 5 seconds of the system activation.
